■ S3-14: Torque Compensation Diminish Speed
Sets the speed level for torque compensation to diminish during the time determined by S3-15. Set as a percentage of the
maximum output frequency (E1-04). A setting of 0.0% disables this function.
■
S3-15: Torque Compensation Diminish Time
Sets the time for torque compensation to diminish when motor speed reaches the level set in S3-14.
■
S3-16: Torque Limit Reduction Time
After Position Lock at stop, S3-16 determines the length of time to reduce the torque limit rate =
■
S3-20: Dwell 2 Speed Reference
Sets the speed reference for the Dwell 2 function.
Note: Setting this parameter to 0.00 disables the Dwell 2 function.

■ S3-21: Dwell 2 End Speed
The Dwell 2 function will end when the drive reaches this speed. A setting of 0.00 will disable the acceleration rate switch
that occurs at the end of Dwell 2.
■
S3-25: DC Injection Gain in Regenerative Operation
In OLV Control, S3-25 sets a gain level for DC Injection at stop (S1-03) for when the regenerative load reaches 100%. At
that time, the current applied during DC Injection at stop is determined as S1-03 × S3-25.
